`
`August 2000. IBM researchers are successfully running Linux and X11 (a popular graphics library) on a device the size of a wrist
`watch, demonstrating the viability of the operating system across all platforms, from large enterprise servers, to medium sized and
`small servers, workstations, desktop systems, laptops and now the smallest intelligent devices.
`
`With Linux rapidly becoming an industry standard, it's important that developers be able to create new applications across all platforms,
`including pervasive devices, and the intent of IBM's research is to further that work.
`
`Designed to communicate wirelessly with PCs, cell phones and other wireless-enabled devices, the watch will have the ability to view
`condensed email messages and directly receive pager like messages In addition, the watch will provide users with calendar, address
`book and to-do list functions. Future enhancements will include a high-resolution screen and applications that will allow the watch to be
`used as an access device for various Internet based services such as up to the minute information about weather, traffic conditions, the
`stock market, sports results and so on.
`
`The watch contains a powerful processor along with eight megabytes of flash memory and another eight megabytes of dynamic random
`access memory. Users interact with the watch through a combination of a touch-sensitive screen and a roller wheel. The watch also has
`both IR and RF wireless connectivity.
`
`Among the technologies IBM is developing for small pervasive devices are packaging, displays, processors, hardware encryption, low
`power systems, wireless protocols, user interfaces, privacy models, middleware, and applications. Other devices that could leverage
`these technologies include PDAs, smart identification badges, and other wearable devices
`
`Several benefits accrue from the use of Linux in small pervasive devices. The availability of source code and a well-understood
`application programming environment makes it easy for students, researchers, and software companies to add new features and
`develop applications.
